Why doesn the APLC use a more natural method of control than chemical pesticides?
The APLC uses a naturally occurring fungus called Metarhizium. Developed in collaboration with CSIRO Entomology, it was used operationally for the first time in the spring 2000 locust outbreak. Metarhizium is sprayed onto locusts (usually when they are in the hopper or nymph stage) as spores suspended in a mineral or vegetable oil using normal aerial spraying equipment. The fungus takes at least one week to kill the hoppers and is therefore not recommended for crop protection. At the moment, Metarhizium is more expensive than conventional insecticides and is being reserved for situations where insecticides cannot be used to control locusts (such as certified organic pastoral properties or environmentally sensitive areas). For further details see APLC Metarhizium.
